The Exposure Triangle is important to know like the back of your hand especially in regards to HDSLR film-making where as the slightest change in sunlight can completely throw out your image. If like me you studied at University its likely you got into your THIRD year before lecturers even started going into this in detail, personally I find that to be a joke. Lucky enough for me my passion for film and the vast amount of online resources meant I learnt this a while ago, but if it wasnt for my intern and venture into HDSLR films I probably wouldn’t have. Anyway, this is a PHOTOGRAPHIC technique that you must know and understand so please read it, it WILL change how you Film forever.
The Exposure triangle is based on three methods of controlling your cameras image – ISO, SHUTTER SPEED, APERTURE which combined create a perfectly exposed picture.
- ISO – the measure of a digital camera sensor’s SENSITIVITY to the light.
- Aperture – the size of the opening inside the lens when a picture is taken, essentially how much light is lets in. This is the QUANTITY of light that is hitting the sensor.
- Shutter Speed – the amount of time that the shutter is open per second, i.e 100/1sec, the will shutter open and close at a hundredth of a second. This is the DURATION of how long the light hits the sensor for. Continue reading
Colour grading is often overlooked by the amateur film makers but its something that can make or break the overall response of your film. A good story with good content is always key but time after time I find my self watching Vimeo films where someone has got their Canon 550D, shot a nice story with some good sympathy building around the characters and they totally skimp out on any kind of post production grading. For me its one of the strongest methods of pulling some one into the story your trying to tell. When you see a film at the Movies chances are its going to be heavily graded, especially a story that rely’s on some kind of fiction as its basis, i.e Terminator Salvation. This is a good example because its colour grading is very apocalyptic to suit when in time it is based, in fact, there’s only two real colours to the film, grey and green. Often people use simple 3 way colour correction methods to colour grade and try to pick out a natural skin tone colour. I feel you shouldnt hold back on changing people’s skin tones and effect the colour of the world the film is based. Start simple, level all the clips to match tonally and get all those skin-tones looking skin tone colour, then push your grade to suit the world your film is based within. A good colour grader will need know all of these tools:
- Lift, Gamma, Gain
- Shadows, Mid-tones, Hi-lights
- Blacks, Mid’s, whites
- Masks(vignettes e.t.c)
Remember when your shooting video and you know your going to grade it after make sure you shoot as FLAT as possible. What do I mean by this, no in camera sharpening , less saturation and no noise reduction. check out this video for setting your flat picture profile’s, this video also goes through some other settings you will need: Continue reading
